<0.01°C (0.018°F) per year

 

Sensor Humedad Relativa (sólo MX2301 y MX2302)

Rango

0 to 100% RH, -40° to 70°C (-40° to 158°F); exposure to conditions below -20°C (-4°F) or above 95% RH may temporarily increase the maximum RH sensor error by an additional 1%

Precisión

±2.5% from 10% to 90% (typical) to a maximum of ±3.5% including hysteresis at 25°C (77°F); below 10% RH and above 90% RH ±5% typical

Resolución

0.05%

Drift

<1% per year typical
